Use quadrilateral ABCD with A(1, 5), B(2, 6), C(3, 3) and D(1, 3) and its transformation A'B'C'D' with A'(-3, 1), B'(0, 4), C'(3, -5) and D'(-3, -5). What is the scale factor of the transformation
Answer:
The scale factor that transforms quadrilateral ABCD to quadrilateral A'B'C'D' is 3
Step-by-step explanation:
Quadrilateral ABCD has the following coordinates
A(1, 5), B(2, 6), C(3, 3) and D(1, 3)
The image A'B'C'D' has the following coordinates;
A'(-3, 1), B'(0, 4), C'(3, -5), D'(-3, -5)
The length of segment [tex]\overline {AB}[/tex] = √((2 - 1)² + (6 - 5)²) = √2
The length of segment [tex]\overline {BC}[/tex] = √((3 - 6)² + (3 - 2)²) = √10
The length of segment [tex]\overline {CD}[/tex] = √((1 - 3)² + (3 - 3)²) = 2
The length of segment [tex]\overline {DA}[/tex] = √((1 - 1)² + (3 - 5)²) = 2
For quadrilateral, we have;
A'(-3, 1), B'(0, 4), C'(3, -5), D'(-3, -5)
The length of segment [tex]\overline {A'B'}[/tex] = √(0 - (-3))² + (4 - 1)²) = 3·√2
The length of segment [tex]\overline {B'C'}[/tex] = √((3 - 0)² + (-5 - 4)²) = 3·√10
The length of segment [tex]\overline {C'D'}[/tex] = √((-3) - 3)² + (-5 - (-5))²) = 6
The length of segment [tex]\overline {D'A'}[/tex] = √((-3) - (-3))² + ((-5) - 1)²) = 6
The scale factor that transforms quadrilateral ABCD to A'B'C'D' is given as follows;
[tex]The \, scale \, factor \, of \, transformation = \dfrac{\overline {A'B'}}{\overline {AB}} = \dfrac{\overline {B'C'}}{\overline {BC}} = \dfrac{\overline {C'D'}}{\overline {CD}} = \dfrac{\overline {D'A'}}{\overline {DA}} = 3[/tex]
Therefore, the scale factor that transforms quadrilateral ABCD to A'B'C'D' = 3

Calculate x
I ll mark you as the brainliest
Answer
x = 18 cm
Step-by-step explanation:
Here, we want to calculate the value of x
let half of x = b
so b is the base of each right-triangle
As we can see, the triangle is isosceles
we can calculate the length of the base of one of the smaller right angled triangle and multiply by 2 to get the full x length
According to Pythagoras’ , the square of the hypotenuse equals the sum of the squares of the two other sides
15^2 = 12^2 + b^2
225 = 144 + b^2
b^2 = 225-144
b^2 = 81
b = √81
b = 9
but x = 2b
x = 2(9)
x = 18 cm
How many pounds of $1.75/lb trail mix should a grocer combine with 3 lb of $3.75/lb trail mix to get $2.95/lb trail mix? I WILL GIVE BRAINLIEST. PLLLLS!!!
Answer:
1.847
Step-by-step explanation:

The grocer should combine 2 pounds of $1.75/lb trail mix with 3 pounds of $3.75/lb trail mix to get 5 pounds of $2.95/lb trail mix.
What is an expression?Expression in maths is defined as the relation of numbers variables and functions by using mathematical signs like addition, subtraction, multiplication, and division.
Let's assume that the grocer needs to combine x pounds of $1.75/lb trail mix to the 3 lb of $3.75/lb trail mix.
To find out how many pounds of $1.75/lb trail mix are needed, we can use the following equation:
$1.75x + $3.75(3) = $2.95(x + 3)
Simplifying the equation, we get:
$1.75x + $11.25 = $2.95x + $8.85
Subtracting $1.75x from both sides, we get:
$11.25 = $1.20x + $8.85
Subtracting $8.85 from both sides, we get:
$2.40 = $1.20x
Dividing both sides by $1.20, we get:
x = 2
Therefore, the grocer should combine 2 pounds of $1.75/lb trail mix with 3 pounds of $3.75/lb trail mix to get 5 pounds of $2.95/lb trail mix.

Find the Volume of a hemisphere that has a radius of 8 centimeters. Round to the nearest tenth
Answer:1072.3
Step by step:
use the hemisphere formula which is 2/3*pie*r^3
substitute 8 centimeters into the equation.
The Volume of a hemisphere is,
⇒ Volume of hemisphere = 1071.78 cm³
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
We have to given that;
Radius of hemisphere = 8 centimeters
We know that;
Volume of hemisphere = 2/3 (πr³)
Hence, We get;
⇒ Volume of hemisphere = 2/3 × 3.14 × 8³
⇒ Volume of hemisphere = 1071.78 cm³
Thus, The Volume of a hemisphere is,

How many pounds are in 6 tons, 200 pounds
Answer:
there are 12000 pounds in 6 tons
There are 12,200 pounds in 6 tons, 200 pounds .
To convert tons to pounds, we need to multiply the number of tons by the conversion factor of 2,000 pounds per ton .
A ton, also referred to as a short ton, is a unit of weight equal to 2,000 pounds .
Given that there are 6 tons and 200 pounds, we can calculate the total weight in pounds as follows :
6 tons * 2,000 pounds/ton + 200 pounds = 12,000 pounds + 200 pounds = 12,200 pounds .
Therefore, there are 12,200 pounds in 6 tons, 200 pounds .

Answer:
x = 3.5
Step-by-step explanation:
3.5 x 3 is 10.5. Triangle two has been expanded each side by 1.5. So multiply 7 (the side with 3x on the other triangle) x 1.5 to get 10.5. To fid x divide 10.5 by 3. This gives you 3.5 as x.
Hope it helps!
Answer:
x = 3.5
Step-by-step explanation:
What we know that the scale factor is 1.5 going from DEF to XYZ (4.5/3 = 1.5; 7.5/5 = 1.5)
So, multiply 7 by 1.5 to get ZX's length. It would be 10.5 units long.
We now know the equation, which is 3x = 10.5
3x = 10.5
Cancel out the multiplication by dividing both sides by 3
x = 10.5/3
Divide 10.5 by 3 to get 3.5
x = 3.5 in this case.

The recipe calls for 2 cups of flour for every cup of sugar.
What is the ratio of sugar to flour?
Given the set of ordered pairs: {(1,3), (2,7), (x,5), (6,4)}.
What is a value for x that would NOT make the set a function? Explain why.
Answer:
2
Step-by-step explanation:
2 is a value of x that would not make the set a function because a function can't have multiple coordinates wit hthe same domain (x-coordinate). 2 is a domain that has already been used in the point (2,7). If this is used in (x,5), the point would become (2,5) and repeat a domain.
Note:
The x-coordinate could also be 1 or 6 because they have been used as domains as well.
